p.s. Now the indicator light is out but all other lights are green. p.s.s. I doubt this matters but I've also tried inserting a CD to force the open but nothing. Robert I hope you've checked the cabling to the monitor. Did something fall off ? Paul |

Regarding the 8200; it did crash last night with a irrecoverable error but it came back and I restarted it to make sure everything was OK and ran scans. Could it be that my video card has gone bad? Robert You can do a quick visual inspection inside if you want, but you're probably going to need a set of trained eyes to look at it. Someone who has spare video cards, power supplies and so on. It's funny that the debug LEDs are all green, which suggests the BIOS is happy with the hardware, but your copy of Windows is kablooie. Maybe the file system is corrupted, the registry has a problem etc. I would be booting with my Linux LiveCD right now, if I could get the optical drive tray open. Just to see if Linux will boot OK or not. Paul |

The monitor cable plugs in then its screwed in
on both sides but yes I checked and everything seems connected. I even thought I may have inadvertently turned the monitor off so pressed the power button just to make sure Robert |

You don't even have to do anything in there, for a quick test. One thing the Macrium may do, when it starts running, is it will scan the disk(s) in the machine, to see what file systems are present. Because, you can actually run backups from that CD. I've done backup operations (imaging) from the Macrium CD. It sounds to me like your monitor isn't responding. But you're in a better position to judge whether you think a monitor that refused to display the screen, could be responsible. On my monitors here, the LED on the monitor turns yellow when there is no signal, and the presence of the yellow LED tells me the monitor has a working power source. If all LEDs on the monitor stayed dark, I would assume a power problem with the monitor. Either the cable is loose, or isn't firmly seated in the power bar. I've had at least one occasion on my other computer, where the monitor power cable (which plugs in from the bottom), managed to work itself loose from the socket. While a monitor backlight could fail to come on, usually there are symptoms of monitor problems in advance, to tell you it's going to happen in a couple weeks. You know all the quirks, and I can only guess at what is going on from this end. If you backed up the 8200, you could also do a restore from backup. But if the Macrium boot CD won't "light up the screen" either, then it's going to be pretty hard to work on the hard drive. I want to see some light come from the monitor first, before contemplating working on the hard drive. Paul |

You answered everything I was going to say
i.e. CD disk we just made and the backup on the external hd. The Indicator on the Monitor shows yellow, so there's a power source. I think what I will try is disconnecting everything and then re-connect everything and see if that does anything. I'll let you know. Robert |

I disconnected everything from the
rear of the computer although I didn't disconnect the cables from the monitor. After I had disconnected everything the floating Dell Self Feature Test appeared on the monitor with red,green,blue and white bars. I reconnected everything but it's still the same. Robert |

Hello Paul,
I took some pics to show you the 8200 since I couldn't take screenshots. It may be difficult to see the lights in some http://i57.tinypic.com/29lzrqf.jpg http://i61.tinypic.com/1j2owj.jpg http://i59.tinypic.com/kcm9tk.jpg Robert |

But such a status doesn't verify the video card output side. The BIOS cannot tell whether the video card VGA output is good, the cable is good, the monitor functions correctly and so on. You can swap monitors, or test the 8200 monitor on an output of the 8500. So that's one way to determine the monitor and video cable are working. If you suspected the video card, you'd need a stock of replacement or test cards to swap in. For example, I have one PCI video card for test purposes, some left over AGP ones, but for PCI Express, I don't have an excess of those. So I'd have to swap between computers if I needed a PCI Express test card. The PCI card is the one I rely on as a universal donor, since my systems here all have a PCI slot. There are some modern computers that are pure PCI Express, so my parts bin isn't as ready to provide test materials for something like that. In terms of failure modes, the most likely way for a video card to fail, is via cooling failure. If the cooling fan on a video card fails, the GPU overheats and that finishes it off. Sometimes, you see colored blocks or other geometric objects on the screen, as the RAM connected to the GPU, coughs up garbage. Those are hints there is a problem. And that's why, one of the observation things, is to check that the video card fan still spins when the power is on. As that tells you whether a cooling failure could be the source of the problem. If there was a power problem (bad power supply), you would think the BIOS would get stuck somewhere, and the diagnostic LED pattern would be different. Now because the BIOS actually checks the power, but because the BIOS might detect some POST test not working right if the power quality was marginal. In terms of general diagnostic approaches: 1) Remove excess hardware, in the hope that the removed item prevents system function. Usually, there isn't a lot of stuff which isn't essential to computer operation. 2) Beep tests. Remove items like video card or RAM, and see if the machine beeps an error code. Which helps prove the CPU and BIOS code are working. But based on your symptoms right now, I'd be swapping a video card. Or doing something so I can see the BIOS screen. Or doing a beep test, just to verify the green diagnostic LEDs are not a fluke of nature. The video card is likely to be AGP, just based on the vintage. The chipset on the 8200 (RAMBus), might pre-date Northbridge built-in GPU designs. Paul |

So what are my options at this point?
Should I try swapping screens with the 8500 (just unplug on and plug in the other). How do I do a beep test? Is there anything else you recommend? If the monitor isn't working than the rescue disk and backup and original disks are useless. Robert |

I would like to have as little as possible
on my computer but I've gotten virus and malware previously and these programs are in place to prevent it from happening again. If Paul or Ken thought it was overkill they would have said so but in fact many of these programs came from suggestions from them. As I understand it, Linux based systems are pretty much virus/malware free like Mac computers so its not a compatible comparison. Robert |

I tried loading the Seagate Sea Tools disc but nothing happened. I still have all my original disks if that helps and Nero, and the Linex CD. This is what the Linex CD he gave me is used for: He gave me instructions on how to answer each prompt to wipe the old partitioning info off the HD, regardless of what operating system was originally on it. He gave me this to clean another Seagate 160 GB HD I have and I believe I still have the original 40GB HD by Westgate? However, I think the other 160 is bad. I switched the monitors with the 8500 and the 8200 monitor came up fine with no problems. So it's the 8200 itself. The video card? As I said the top fan sometimes needs a nudge but more and more its been starting on its own. If you can point me to a video card I can purchase it and install it. Otherwise, what else might it be? Motherboard corrupted? Software corrupted? Thanks, Robert |

That's my opinion. ******* Safe hex as a security approach requires considerable effort, and comes with no guarantees. I don't think it's a fair tradeoff in this case. There's no point to being tipped over, again and again, by malware and adware. Let the tools do the work. The 8500 has an excess of horsepower, so that part of it is not an issue. The 8200 on the other hand, having too much junk running on there, probably saps a bit of its energy, as it's a single core CPU. But I'd still keep it locked down, as it's then less work to fix later. Paul |

Motherboard corrupted? Software corrupted? Thanks, Robert I'm trying to be mindful of your budget here. I don't recommend buying a lot of hardware, unless it will not cause a hardship, and you are likely to use the hardware later. Take my spare video cards for example. They've seen many uses over the years, and since they were bought when the AGP format was younger, there were plenty of years left for them to see usage. At this point in time, AGP cards are getting harder to find. And you can't use such a card in your 8500, which is likely to have a PCI Express x16 video card. I would recommend visiting a local computer recycler if you know of one. Ask for a card that is known good - tell them what you intend to do with it. Most of the cards they'll have, will be $50 to $100 stuff, rather than having a pile of $500 gamer cards. And that's great, as then the card won't use more than about 35W of electricity. The idea is, to get a card for $10 to $20. An ideal card would be something like an FX5200 (with cooling fan), as those span all the way from Win98 to Win7 on drivers. There is no driver for one of those for Win8 or Win10. And the card does not have to be AGP. A video card with PCI interface, would also work. But, if you get the AGP, that could serve as a permanent replacement. I only use PCI based video cards for short term usage, because they are slow as molasses in winter. They serve as a display in an emergency (like when flashing the VESA BIOS chip on your "good" video card). But other than that, my PCI card stays in the box. Most of the time the PCI card is OK, but if you have a QuickTime movie open, and you attempt to drag the window across the desktop, it "stutters like a *******". And I don't particularly like that :-) Card types: PCI 133MB/sec max AGP 266MB/sec "1X card" 2128MB/sec "8X card" PCI Express 4000MB/sec PCI Express x16 Rev.2 8000MB/sec PCI Express x16 Rev.3 250MB/sec PCI Express x1 Rev.2 You can see the PCI is pretty slow. But it does make a great card "just to see the screen in the BIOS" or for "a quick debug run". But not as a permanent video card. ******* This article will help you with AGP compatibility. http://www.playtool.com/pages/agpcompat/agp.html Your 8200 could use an 850 or an 850E Northbridge. From the Playtool table... Intel 850 AGP 1.5V Motherboard Using a row out of the upper table, it works with virtually everything I would want to own as an AGP video card. So that's a good sign. AGP 1.5V Motherboard Won't fit in slot Works at 1.5V Works at 1.5V Works at 1.5V Works at 1.5V Only an AGP 3.3V card won't fit. The socket will have the notch on the 1.5V end. See the picture. Your 8200 will either be the second one down. Or it could be the bottom one. The bottom one is AGP Pro, and the extra pins just carry more power. http://www.playtool.com/pages/agpcompat/agpslots.gif The idea of the keying (voltage) plug, is it checks for compatible cards. If you use this picture as a reference, you *don't* want the middle card. Both the left and right cards, have a slot for 1.5V. And that means the left and right cards fit. The right-hand card is "universal" type. You also should not have a problem with slot power. Slot power issues (3.3V) were present in the P3 era or so. I do not expect a problem with that aspect. So the job is reasonably simple. If you absolutely must waste good money on this, EVGA 512-A8-N403-RX GeForce 6200 512MB 64-Bit DDR2 AGP 4X/8X Factory Refurbished $26 http://www.newegg.com/Product/Produc...82E16814130635 A 6200 is a reasonable cross-generation card. That one has universal keying. The refurbished sometimes means, these are new cards used for warranty replacement work. I got a similar card in my current computer, and saved a bit of money on it. What I don't like on that card, is it is convection cooled. If your computer case seems to have decent airflow, that might work for you. I've had mixed results with cards cooled that way. One ran just fine. The other became unstable only when playing a computer game, but was otherwise OK. When I buy cards like that now, I mount a case cooling fan next to the card, inside the computer case. And no, you *cannot* buy an easy-peasy mounting bracket for this - you must descend to your basement shop and *make* one. For the rest on Newegg, they want too much money. The $25 card will work fine, for your debugging work. If it runs too hot for some reason, then you're going to need to become a mechanical engineer and set up a cooler next to it :-) This is the custom cooler for my newest machine. The yellow thing in the center of the picture, is a leg that holds up the CPU cooler (which is a heavy piece of metal). The fan is relatively hard to make out in that picture. It's an 80mm fan. The three wire cable runs off to a motherboard fan header. The nylon ties go through the holes on the fan plastic body, and hold the fan to the metal support. The cheap video card is just above the fan assembly. http://i62.tinypic.com/slpamc.jpg Have fun, Paul |
